THE APPLE CULTURIST. 



Fig. 90. 



tent-caterpillar, as to the name by which the foe may be 

 called. 



We herewith give life-like illustrations, from the " Amer- 

 ican Entomologist," of both the Plum Curculio and the 

 Apple Curculio. Figure 90 is a magnified representation 



of the Plum Curculio in its 

 various stages. The mag- 

 nified grub at a represents 

 the curculio in the larva 

 state. The horizontal line 

 beneath it represents the 

 natural length when it is 

 found in the fruit. At b 

 the insect is represented in 

 the pupa state. The ver-

greatly magnified. Its col-

 is represented as magnified several times. The mark be-

 grown 'insect. The color of this "little Turk" is some- 

 times brown, black, or of a clay-yellow. At d a curculio of 

 full size is shown on the surface of a small plum, in one side 

 of which the crescent mark of the curculio's proboscis ap- 

 pears, such as is made on the young fruit when an egg is 

 deposited beneath the skin. Fig. 91, On the opposite page, 

 represents the Apple Curculio, which, to appearance, is a 

 very different insect from the Plum Curculio. At a is a 

 diagram of the depredator of natural size. At b is a mag- 

 nified side-view. At c we have a back view of the same 

 insect. The usual color of this insect is a dingy gray, in- 

 clining to red rust behind. The Apple Curculio spreads
